PERFORMANCE
A.025P PLASTIC RUBBER-FITTED
Height ................................... 180 mm (7.1")
Width .................................... 145 mm (5.7")
Depth ................................... 132 mm (5.2")
Est. Ship Weight ... Polypropylene 1kg (3 lbs)
1 kg (PVDF 3 lbs)
Air Inlet ..................................... 3 mm (1/8")
Inlet .......................................... 6 mm (1/4")
Outlet ....................................... 6 mm (1/4")
Suction Lift ......................4.14 m (13.6' Dry)
9.32 m (30.6' Wet)
Displacement per
Stroke .................... 0.018 l (0.005 gal.)
1
Max. Flow Rate .............. 12.1 lpm (3.2 gpm)
Max. Size Solids .................. 0.4 mm (1/64")
1
Displacement per stroke was calculated at
4.8 bar (70 psig) air inlet pressure against a
2 bar (30 psig) head pressure.
Example:
To pump 3.8 lpm (1 gpm) against
a discharge pressure head of 2.8 bar (40
psig) requires 4.1 bar (60 psig) and 3.2 Nm
3
/h
(1.9 scfm) air consumption.
Caution: Do not exceed 8.6 bar (125 psig) air
supply pressure.
Flow rates indicated on chart were determined by pumping water.
For optimum life and performance, pumps should be specified so that daily operation parameters
will fall in the center of the pump performance curve.
